Grass.....Grass....and more Grass

I am lacking knowledge in the grass displacement and when the right time to use it is… Does anyone have a sticky or something they can post as far as materials, displace settings, scale…etc…etc… I have found a couple threads but the links are now broken to the files

Thanx

Eric

for grass I have a few grass maps I mix for the diffuse to theres little or no tiling, and then I have a noise map I created in photoshop for the displacement…cant recall exact settings, I usually relearn it every time…lol
